Instead of regular sunglasses what I wear are tinted lenses; ones that are colored a color. So for example, my lenses are blue, because my blue lenses reduce my light sensitivity.

Instead of just reducing the amount of light coming in this is saying "the color affects me too" and changing the color makes it easier on me.

So, one thing you could do on the color idea is to see if its easier to look at the computer with different background colors. It might help. It might not. If colors help that'd be great because something that helps is great.

There's a bunch on color based things on http://irlen.com/

My vertigo is also the floor is not stable primarily, though my vertigo is associated with hearing, not sight. It's not nearly as severe as yours. The fact that topamax is helpful is great! It's one of the medications I'm taking for my migraines so it might be helping my vertigo too. There are multiple things I deal with I found out after its helpful for beyond my migraines, which is why I'm on it.


So, this is an area I'm less good at but some immediate suggestions:

-Again reducing light coming in. Do you know how horses have blinders so they can't see peripheral vision? Put blinders like that on your glasses/tinted lenses/sunglasses. I've found that the worse light sensitivity is frequently, though not always, for me associated with my peripheral vision and if I cut that out I can increase the amount of time before symptoms show up.

-Reduce the amount of salt you eat. Vertigo is frequently worse with higher salt diets.

-Any other sensory sensitivities you have, deal on them too, make sure to get them dealt with, not just this vision one. It's easy to get tied up in the one that's worst, but if you only look at the one that's worst, the other ones make your body less able to cope with that one. I have been really bad with this one in the past.

-Check different types of computer screens to see if some are easier than others. An LED backlit screen might be easier than a standard LCD. It also might not be. Look at them and see how you feel, different people are different.

-Lighting in the office. Manage this. How do you react to florescent lights? Most of us with light sensitivities HATE them, if you do, deal with that and see if you can get alternate lighting if that's what you have. Sometimes that's the worst for people and getting rid of that solves most of their problems.

-And simply, find ways to deal with the vertigo that's there. I carry a folding cane for when I need it. It helps with making it less tiring to walk even though I don't need it always that I use it. Sometimes I need it, usually when I use it I could get away without it, but this way I don't need to put the effort in there, and can put it in other places. I suspect you've done a lot here, but don't undervalue it. Dealing with symptoms and making them less exhausting is sometimes what to do.

Oh, and one more possible area to look into if you feel its the right way:
-Looking into things that mean you can do things with your eyes closed if that helps so as to not deal with the light attacking you.

If you want help with that last one I can help with things like finding screen readers or such, depending on what you feel you need.
